A 60-gram stress ball was thrown into the air, and it has a velocity of (9.8 m/s)i – (2.1 m/s)j. Simultaneously, a 34-gram knife was catapulted from a distance and travelled with a velocity of (50.3 m/s)j + (70.0 m/s)k. At 10 m above the ground, the knife hits the stress ball, piercing through the soft, squishy ball. Calculate the exact position where the knife and the stress ball will hit the ground, relative to the point directly under the point of impact. Note that j is directed upwards.
